I have been looking at encapsulating our homes foundation for years. I finally found a great price in SC.with a quality barrier.

This makes a nice cushion under the 20 mil vapor barrier we bought. I first tried to cut it with a box cutter, but the box cutter couldn't puncture the material. Then I got out a sharp pair of scissors and that worked great for cutting the pieces we needed. So, I think the felt will really protect vapor barrier from any sharp objects or stones. We pulled more than 50 rusty nails out of the dirt and I wanted to make sure that if we missed a nail we wouldn't have a hole in the vapor barrier.

My 600 sq ft metal building has a dirt floor and suffered from high humidity leading to mold and mildew. I placed the 20 mil with the silver side up, taped it to the metal frame and placed pins about every 18 inches. It looks great and has dramatically reduced humidity. An excellent product. I do suggest that when drilling the holes in the metal frame that instead of drilling 1/4” it was better to drill 7/32” holes. It made the plastic pins tighter.

 

Put the 12 mil barrier under my 10 yr old house. Stopped the dirt smell and the humidity problem. Awesome product. Easy to install. Recommend getting the tape that's used to secure the barrier to the wall.

This vapor barrier is very tough. Even over an area where I had stone base the vapor barrier didn't fail. I've crawled over it now many times and only have seen some minor strain marks on the stone. This product is tough but easy to work with. Highly recommend it!
